I can't tell when a LCD is running at 60hz, however I can tell when a CRT is.
That is probably because CRTs flicker like shit at 60hz
Also, when it comes to response times, I'm sure 2ms must be pretty fucking good, I mean, I have 8ms and unless I'm playing an NES game or something, it's not going to be noticed
btw response time and refresh rate are pretty different issues
